LACTOSE – C12H22O11 Chemical and Biochemical Properties Lactose is very stable and inert from a chemical point of view. It has no significant tendency to react with the drug or other components of a formulation. Some remarks on the chemical properties of lactose are useful however‚ the low hygroscopicity of crystalline lactose supports its virtual chemical inertness. Most chemical reactions of lactose occur noticeably only in aqueous environment. Because lactose has a very low tendency to attract

Abstract Lactose Intolerance is a condition that effects people who do not produce enough lactase to digest lactose. There are three different types of Lactose Intolerance that are caused by the small intestine and the amount of lactase produced. Lactose Intolerance effects those who have the condition by causing pain and making them uncomfortable ("Lactose intolerance"). Lactose Intolerance Introduction Lactose Intolerance is a condition that effects one out of every ten Americans

Lactose Intolerance Have you ever tried to drink milk or other dairy products and felt sick? The reason they get sick is because they are lactose intolerance and they are unable to digest large amounts of lactose. The reason this happens is because they have a shortage of lactase which is normally produced by the cells that line the small intestine. Lactase breaks down the sugars into a easier form that can then be absorbed into the bloodstream. When there is not enough lactase present

Final Paper 5/2/2013 Lactose Intolerance The topic I chose to research was lactose intolerance. Lactose is the natural sugar found in milk. Lactose is made by joining a molecule of glucose with one of galactose (Willett 101). We are born with the enzyme lactase‚ which digests and breaks down the lactose. Some people do not digest lactose well due to a lack of lactase or their body may make lactase that does not work properly. Not all people with a lactase deficiency have digestive symptoms‚ but

Indole Test: Procedure: We obtained a tube of tryptic soy broth (tsb) and inoculated it with our unknown bacteria. Then placed our tube in the incubator at 37 oC and allowed for it to grow overnight; the following day we came back to finish our confirmatory test. To do so‚ we added 10 drops of Kovac’s reagent to the tube and watched for a color change. Results: A positive test‚ indicated by a red/pink layer‚ is due to the tryptophan being hydrolyzed producing indole‚ pyruvic acid‚

testing in this experiments are: Lactase Enzyme and Lactose. Lactase is a protein located in the human small intestine‚ while lactose is a term to define the sugar found in milk. Milk is a substance that contains nutrients necessary for our bodies‚ however‚ some people are unable to consume lactose related products‚ and so they are medically classified as Lactose Intolerants. The purpose of this experiment is to examine and illustrate the way that lactose gets affected by lactase enzyme whenever lactase

Lactose IntolerancePeople who are lactose intolerance are unable to digest significant of lactose‚ the reason being is and inadequate amount of enzyme lactase2. Individuals with lactose intolerance believe that they are allergic to milk and a lot of other milk products. An estimated 30 million to 50 million American adults are lactose intolerant. However a milk allergy has something to do with the proteins in milk rather than the lactose. To determine that you have trouble digesting lactose you must
Premium Milk Lactose intolerance
Lactose intolerance is the inability to digest significant amounts of lactose‚ the predominate sugar in milk. This inability results from a shortage of the enzyme lactase‚ which is normally produced by the cells that line the small intestine. Lactase breaks down milk sugar into simpler forms that can then be absorbed into the bloodstream. While not all people deficient in lactase have symptoms‚ those who do are considered to be lactose intolerant. Common symptoms of lactose intolerance are: nausea

that breaks down fat. The fat hydrolysis test was positive‚ showing K. pneumoniae produces lipase and can break down fats. The indole test was performed to determine if our bacteria can break down tryptophan via the enzyme tryptophanase. Our indole test came back negative‚ meaning K. pneumoniae does not produce tryptophanase and does not break down tryptophan into indole‚ ammonia‚ and pyruvic acid. The urea test was performed to determine if urea is hydrolyzed via the enzyme urease. The urea test

Lactose Intolerance is an intestinal condition caused by insufficient synthesis of the intestinal enzyme lactase needed to break down lactose (Keith‚ Nichols‚ Reed‚ Kafer‚ Miller 2011). So what does this exactly mean? People with lactose intolerance have trouble digesting lactose‚ the natural sugar found in milk and milk products. Undigested lactose can upset the stomach and cause diarrhea. Most people who are lactose intolerant are able to consume some lactose without symptoms. However‚ many people
